CUTTING, FILING, AND SCRAPING IMPLEMENT I Filed Feb. '6, 1932 ununllI-u .mmunn llllllllll He. 1 39 so INVENTOR ATTORNEY Patented Jan. 2, 1934 UNITED STATES PATENT OFFICE CUTTING, FILING, AND SGRAPING IMPLEMENT 15 Claims.

The subject matter of this invention is a tool having oppositely disposed cutting and filing members pivotally mounted in a holder or casing formed by a pair of closely spaced discs.

It is an object of this invention to provide an improved filing, cutting and scraping implement having relatively few parts which may be easily and quickly assembled and which may be produced at a relatively low cost.

More particularly, another object of the invention resides in securing the opposed discs or coin shaped elements forming the holder in which the filing and cutting members are operatively sustained without employing supplementary fastening devices such as rivets or the like.

A further object of the invention is to provide aholder having two components one of which embodies a centrally arranged spring anchoring device for retaining an intermediate portion of a spring which has its free portions extending laterally beyond the anchoring device, which free portions cooperate with respective cutting or filing members to maintain the latter in a folded position within the holder or exposed position ready for use.

A still further object is to provide the cutting, filing and/or scraping elements each with a curved portion adapted to be arranged flush with the contiguous edges of the holder, the elements each comprising a protuberance which extends slightly beyond the limits of the holder when the members are folded or closed, which protuberances constitute means for readily swinging a respective member beyond the holder.

The manner in which the invention may be carried into effect together with the more detailed objects and advantages of the invention may be best understood by reference to the accompanying drawing forming a part thereof in which:

Fig. 1 is a plan view of the tool according to my invention.

Fig. 2 is a side view of Fig. 1. Y

Fig. 3 is a view of the tool partly broken away to show the interior construction and also illustrating in dotted lines the elements swung out of the holder.

Fig. 4 is an inside-view of one of the complements or discs of the holder or casing.

' Fig. 5 is a section on the line 5--5 of Fig. 4 and Fig. 6 is a sectional view taken on the'line 66 of Fig. 4.

Referring to the drawing, the holder or casing according to the invention comprises a pair of closely spaced discs or components 10 and 11. In the form illustrated, it will be noted that disc 10 has on its inner face spaced fulcrum posts or studs 12. Preferably, these posts are cast or made integral with disc 10.

Adjacent each fulcrum post 12, disc 10 embodies a stop lug or shoulder 13. These shoulders are diametrically arranged and are preferably cast integral with the disc.

Each shoulder also includes a fiat face 14 on which the other component 11 of the holder is seated when coin shaped parts or discs are assembled prior to fastening, the shoulders 14 also constitute spacing elements for holding the inner faces of components 10 and 11 a predetermined distance apart.

Viewed from Fig. 6 it will be noted that a terminal or free portion of a post 12 is a further distance away from the inner face of disc 10 than the flat face 14 of an associated shoulder.

Cast integral with component 10 and extending from inner face thereof is a spring anchoring device generallly designated 15, This device is arranged across the origin of disc 10 and between opposed fulcrum posts and stop shoulders. According to the form illustrated the anchoring device comprises a pair of spaced retaining instrumentalities or lugs 16 and 17. These lugsdefine a tortuous or wavy channel 18 adapted to receive a crimped or intermediate arcuately offset portion 19 of a relatively light weight and elongated resilient rod or spring generally denoted 20.

The wavy channel is formed by a crown shaped projection 21 which extends from lug 16 of the spring anchoring device and projects into but spaced from the side of reentrant recess 22 of thecomplementary lug 17, the channel beingjust wide enough to receive intermediate crimped or offset portion 19 of the spring 20 which is held anchored in the channel by coaction of the corresponding shaped faces of the undulating por tions of the crown projection and recess of the complementary anchoring lugs.

Arms 23 of the spring project laterally of the anchoring device and the free terminal portions thereof extend between and within proximity to a post and an adjacent stop shoulder.

Pivotally mounted on each post 12 is a blade or manicuring element 24. In the form illustrated two posts are shown. To one of the posts is mounted a blade having a sharp cutting edge 25 and a pointed scraping end 26. To the other fulcrum post 12 is mounted a blade including knurled or roughened faces as 27 for filing and a pointed scraping end 28.

Each blade is provided with a curved outer face 29 which is flush with the outer circumferential faces of the spaced discs together with a projection 30 which extends slightly beyond the discs when a blade is within the holder whereby it may be swung from a closed or folded position in the holder indicated by full lines in Fig. 3 to an operative or exposed position for use as disclosed by the dotted lines in the same figure.

It willbe noted that in the concealed or folded position of a blade, a scraping porton as 26 thereof is against an associated stop shoulder 13 which limits inward movement of the blade between the discs.

Each blade includes a laterally extending terminal perforated ear portion 31 comprising cam faces 32, 33 and 34, a pair of the faces being interconnected by a suitable curved corner 35, the ear portion of a blade being swingably mounted on a post 12. In the folded position of a blade, the free portion of an arm 23 of the spring bears against an adjacent cam face 32 and this action locks the blade in place between the discs of the holder. In this position its scraping end- 28 is against an opposing stop shoulderlB.

Cam face 33 bears against an adjacent free end of the spring and holds a blade locked in an intermediate position between folded and open positions. Cam face 34 abuts the free end of the adjacent spring and holds the blade locked when extended for use, and in this position of a blade a rear rectilinear face 36 abuts an adjacent shoulder 13.

With the spring anchored and the blades mounted on their posts, the rear discs or complement 11 is arranged in such manner that its perforations 3'7 receive the opposed posts 12.

Theinner face of the disc llis uniformly flat and portions thereof lie fiat against the flat faces 14 of the'stop shoulders 13. The outer face of disc 11 is also flat.

Having arranged disc 11 on posts '12, the free portions of the latter may be'slightly upset or struck to fasten this disc against the flat faces 14 of the stop shoulders or the free terminals of the posts may be snapped into perforations 3'7 and a slight pressure on the disc 11 fastens the latter to the posts.

Of course 'to enhance the appearance of the coin shaped implement heretofore disclosed, it is within the scope of theinvention to providea suitable design to the exposed sides of the discs. In actual practice, disc 10 may be a diecasting and disc 11 a stamping from sheet metal.

In order that the'coin shaped implement may be properly supported or hung from a watch chain or fob or the like, one of the shoulders 13 is provided with a perforation 38 adapted to register with marginal opening 39 of the disc 11 for receiving a link or annulus of a suitable construction usually associated with a watch chain or fob asis well understood.

-As many changes could be madein the above method and many apparently widely different embodiments of the invention could be devised without departing from the scope thereof, it is intended that alfmattercontained in the above description or'shown in the'accompanying drawing shallbe interpreted as illustrative'andnot in a limiting sense.
